- all spanish words are translated here Hoping to attract more commuters, an urban transportation company plans to run express bus service from a suburban terminal to the city's financial center. These buses should save travel time. The city decides to carry out a study of the effect of four different plans (for example a special lane and synchronized traffic lights) on the travel time of buses. Travel times (in minutes) are measured for multiple business days during peak hour travel when each of the plans is being implemented. The results appear in the table below.

To study this question, you survey 200 students and obtain their average weekly coffee intake. Data are collected using a between-subjects approach on 50 Freshmen, 50 Sophomores, 50 Juniors, and 50 Seniors. The data are presented in terms of how many cups of coffee, on average, each class drank per week. Here is what was found: Freshmen (M= 11.5, SD=3.1) Sophomore (M= 12.1, SD=2.2) Junior (M= 15.3, SD=2.5) Senior (M-19.8, SD=3.0) F(3,196)= 6.5, p = .004, n² = .32, Tukey's HSD = 2.4 Based on the nature of the independent variable and design of the study, what statistical test should have been used?
